hello everyone,
i am a student and new to plcs. i have a small weighing project. in this i have to use 2 load cells, 3 pneumatic actuators. there are two hopers. 1st one controls the flow.when 1st get filled a door opens and put them into the second. using load cells i have to get the weight of the 2nd hoper. and open the door using actuators.
at the end of the day i have to display the total weight which passes through the second hopper.
i am going to use a 4 Channel Strain Gauge Sum Amplifier (http://www.aliexpress.com/store/pro...gnal-output-0-5V-4-20mA/607949_344806141.html) to load cells and input the 0-10v analog signal to plc for controlling. i want to sum all the readings and display at the end.
my questions,
1. can i use siemens logo plc (OBA6) to this project.(it has 4 analog inputs)
2. or else what is the cheap and best plc for this
3. have any one used above mentioned amplifier.
4. if some one can please send me a example ladder program which used for a weighing application like this.
